Super-Duper Mart Poster

My first try at some Fallout 3 work. I really wanted to make my own Nuka-Cola's and noticed some work on dA. Thought i'd give the super-duper mart poster a go as i love all the retro artwork bethesda have done. anyway this is only the begining so i open to suggestions. i know there are plenty of f3 fans on here

obviously not my original idea, tis bethesdas etc

done with limited skill on Photoshop.
